What it is
A suite of two browser demos for developers and demo viewers: Mirror, a real-time message tone analyzer scoring 8 tone dimensions, and Jev Maze Runner, a game where Jev picks paths through a random 15x15 maze.
How it uses Jev
The README does not specify which Jev primitives are used or how state is passed. It states Jev makes sub-100ms strategic path decisions in the maze and evaluates 8 tone dimensions on every keystroke pause in Mirror, with results driving the UI.
Technique worth stealing
Route browser calls through a Cloudflare Worker proxy so JEV_API_KEY stays server-side and CORS is handled.
Try it
Deploy worker.js with wrangler, set WORKER_URL, then serve mirror.html and maze.html via python -m http.server.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
